Benefits of technology

The patent describes a technology that maintains the appearance of a vehicle's external switch module while securing its functionality. This is achieved by laminating a foam and transparent skin after a groove is formed in the lower surface of an upper substrate. The technology also allows for the display of symbols on the substrate, making them easily visible inside the vehicle. Additionally, the patent discusses the use of a protrusion groove to prevent foam from adhering to a light guide plate during foam molding. Furthermore, the patent notes the use of an accommodation groove to improve the clearness of symbols and fix the switch module, as well as the use of a transparent resin and transparent paint without the need for a separate process of boring a hole in the transparent resin. The use of a thermo plastic elastomer material in the transparent resin simplifies the process, while the high affinity of the resin with the substrate and light guide plate ensures compatibility during injection molding.

Problems solved by technology

Therefore, drivers who get out of the vehicle may not check a symbol inside the vehicle through a window.
In particular, after a door is locked or unlocked, when drivers get out of the vehicle, the drivers tend to check the symbol through the window, but such a demand may not be satisfied.
However, the finishing treatment is postprocessed and thus may not attractive and likely to drop a price of the vehicle.
Meanwhile, in the patent document (Korean Patent Laid-Open Publication No. 10-2017-0074740), since a switch is provided on a substrate, the same problem arises similarly to the patent document (Japanese Patent Publication No. 4218660).

first exemplary embodiment

[0044]As illustrated in FIG. 4E, a soft upper trim 100 for switch assembly of a vehicle door according to the present first exemplary embodiment includes an upper substrate 200 to which a switch module 1 is assembled, a light guide plate 300 assembled to the upper substrate 200, and a foam 400, and a transparent skin 500 laminated on an upper surface of the upper substrate 200 around the light guide plate 300.

[0045]The upper substrate 200 is an injection-molded product made of an acrylonitrile butadiene styrene (ABS) material.

[0046]As illustrated in FIG. 4A, a through-hole 210 is formed in the upper substrate 200 along a vertical center line thereof. A recessed groove 230 having a diameter greater than a diameter of the through-hole 210 is formed in a lower side of the upper substrate 200 so as to communicate with the through-hole 210.

[0047]The through-hole 210 and the lower recessed groove 230 become a space in which the switch module 1 is caught and assembled as illustrated in FIG...

second exemplary embodiment

[0084]As illustrated in FIG. 7, a soft upper trim 100′ for switch assembly of a vehicle door according to the present second exemplary embodiment includes an upper substrate 200′ to which a switch module 1 is assembled, a light guide plate 300 assembled to the upper substrate 200′, a transparent resin 400′ injection-molded on upper surfaces of the light guide plate 300 and the upper substrate 200, and a transparent paint 500′ applied on an upper surface of the transparent resin 400′.

[0085]The upper substrate 200′ is a component injection-molded using polypropylene (PP).

[0086]As illustrated in FIG. 7A, a through-hole 210 is formed along a vertical center line of the upper substrate 200′. A lower recessed groove 230 having a diameter greater than a diameter of the through-hole 210 is formed in a lower side of the upper substrate 200′ so as to communicate with the through-hole 210.

[0087]In addition, an upper recessed groove 240′ having a diameter greater than the diameter of the throug...

Abstract

Provided is a soft upper trim of a vehicle door, in which an upper substrate, foam, and a transparent skin are laminated, and particularly, to a soft upper trim for switch assembly of a vehicle door, in which a switch, which is configured to preserve continuity of a transparent skin and display lock and unlock symbols on the transparent skin, is easily assembled to an upper substrate, and a method of manufacturing the same.

Description

BACKGROUND1. Technical Field[0001]The present invention relates to a soft upper trim of a vehicle door, in which an upper substrate, foam, and a transparent skin are laminated, and particularly, to a soft upper trim for switch assembly of a vehicle door, in which a switch, which is configured to preserve continuity of a transparent skin and display lock and unlock symbols on the transparent skin, is easily assembled to an upper substrate, and a method of manufacturing the same.2. Description of Related Art[0002]A foamed skin trim 70 (see FIG. 1) at a door upper trim side for a vehicle is disclosed in the patent document (Korean Patent Registration No. 10-1087875).[0003]That is, a substrate for a door trim of a vehicle is divided into an injection-molded upper substrate, a center substrate, and a lower substrate. The three divided substrates are connected through screws or the like.[0004]In addition, a foam-molded foam 50 and a transparent skin 60 are further laminated on the upper s...
